Older or just plain heavy displays are no match for the weight this mount can hold. You will be hard-pressed to find a display on the market today that is too heavy for the AM500-U. Fully extended the mount sits 24.5 inches from the wall using heavy duty dual arms and is 8.5 in fully collapsed. These articulating arms allow even the heaviest display to be pulled away from the wall with relative ease for service or alignment. The mount is great for digital signage, commercial building, command and control, government, and entertainment applications. Also, this product ships in two boxes (see weight and dimensions below).
